This Atlas (nee MTH) RPO was a special run done by Berwyn's Trains. It arrived painted silver and FW&D did not have any silver RPOs on their roster. I added some extra roof vents to the clerestory roof section which was common on Burlington head end cars. I removed all the lighting and the pickup rollers, and blanked out several windows. Pullman green paint, Microscale decals, slight weathering, and plenty of dullcoat finished the job. Relettering this car caused me to realize I had mistakenly lettered a full baggage car with the same number. That #33 became 103 to correct the mistake.
This type of RPO could be seen on both the Texas Zephyr and the unnamed mail trains.
